IMPROVEMENT IN `SEED-SOWER.`

To ALL wnoM 1r MAY conchas:

Beit knownthatfI', FfREDEnIcK W. Tlnio'mpf Bristol Station, in the countyoi'` Kendall, in the lState of A Illinois, have'iuvented ,certain new and useful Improvements 'in Seed-sewers and I do herebydeclare that the following is a full and exact description'thereof.

-I will proceed to describe what I consider -the best means of' carrying out my'i-nvention, and will afterwards l designate lthe points which I believe to bve'new. The accompanying drawings yforma part of this specification.

Figure 1 is a'pl'an view, with: a portion of the lop broken away, the better to exhibit the interior. Figure ,2 is a .vertical section, v

`Figure 3 isa cross-section.

Similar letters oaefereuce indicate like parts-in all the figures.

' v'.lints areemployed merely to aidi'n distinguishing parts,and do not indicate' material. The material may i be. wood and iron.

A is a fixed4 framing,'provided with thills for theattachment of a horse; Axis-a cover hinged to A,.as l

represented, carryinga seat for the driver. y

. B is a shaft, extending the whole length of the machine, on' which the weight of the machine is carried, by A the aid of two'wheels, B1. and B. The wheel E2 is fixed upon a sleeve, b2, which'is provided with teeth, as indicated, and is pressed laterally into corresponding teeth fixed on the shaft B, by means of the spring bl, as Arepresented. l l l The interior of the casing A serves as the receptacle for the'seed. A large .portion of the bottom of this receptacle is iilled up with blocks` of wood A?, as indicated, in order that the seed may not remain in these portions afterthe seed-receiving cavities have ceased to be lled, when the seed Ais nearly exhausted.

The seed-receiving. cavities are formed partly iuthe parts D, which are iix'ed immovably on the 'shaft B,

and partly on the part E, which is adapted to slide endwise on the shaft B, and thereby, atha siugleoperation',

vto uniformly enlarge 'or contract the cavities. M denotes the eavities in whichI the seeds are received,land

which are thus enlarged and diminished at pleasure. The machine represented contains v'e sets of'lthese seedmeasuring devices. `A greater orless number mayjhe used in any instance desired. I i I Itwill be readily understood 'from the drawings thatthe seed vin the frame A'falls by gravity 'into the several spaces M as theyare'presentedby the rotation ofthe shai't B, and, tha-t'the remainder is kepebaek by the cut-olf F. l.When the cavities M have passed the cut-olf F andlha've passed around near the under side of the shaft B, tlie'seeds are precipitated by gravity upon an inclined board, G, which is hinged to the framing A at the points g, and is supportedat the proper elevation by the chain H. This chain hooks upon the hooks I,

s o thatthe inclination of theiboardGi'maybe varied .by shortening o r lengthening the chain, one link at a, time.

'lhe seed on striking the board G- Vare'delelcted and scattered. The upper surface of the boardisgrooved, as indicated, by G', the better-to eiiect this end. i I

Another mode-of effecting the scattering, is indicated as applied at two points in the machine, where J J are plates of copper, secured Vbynails or equivalent fastenings j, in suchmanner as to be raised in themiddle,

-and `thus to present a surface admirably adapted to .deflect the seed and spread it in the same manner as. broad castFsowingr The nature of copper, by oieriug very great frictinal resistance to any object sliding over it, is peculiarly adapted uniformly to retard and scatter' the seed. I I l Theparts areixed tothe shaft B by the aid of the screws zi, which pass through slots in the sleeve E. The end of thepshaft B is threaded, and carries a-nut, R, by turning which the shaft B, with its connections D,

is moved endwise relatively t'o the sleeve E, and all the several connections D being moved. simultaneously, and

to the sameextent, itfollows that all the seed-measuring cavities M are simultaneously increased or diminished in capacityby each turning of" the screw-nnt R. The spring C, which forces` the wheel Bz and its connected sleeve b2; intoithe toothed spaces,and thus.v couples or connects -thewheel B? with the sleeve E, also takes up all l the slack in the conne'ctionhetween the shaft B and the sleeve E. Whenthe nut is turned in one direction, it. diminishes the capacityof-v the cavities M, and compresses therspriug C when it is turned in' the other direction, it allows the spring C to expand," and thus to simultaneously increase the capacity of the cavities M.

K is a slide, operated by the hand-lever L, turning on the pivot Z, and adapted to push the wheel B2 and its sleeve b2 ont of contact with the teeth P on the shaft'. When these parts are thus disconnected, the machine may be transported along the road to :my distance Without turning the seeding-shaft or its'eonnections.-

The weight of the entire machine is transmittedthrough the bearings A3 to the sleeve E, and is thereby supported on the wheels B B2. The simplicity of this arrangement' saves much expense, and avoids much risk of derangement. Other means than the screw-nut R may be used to move the rod B within sleeve E. v

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows:

I claim, in a seed-planting machine, so arranging the sleeve E as to perform the doublefunetion of carryngthe seeding-devices, and of supporting the weight ofthe machine, substantially 'as above set forth.
